The 12z HRRR doesn't look too bad from hours 40-48, it put down 4-5" over those 8 hours, and there's still more it's showing. I know it's at the edge of it usefulness at that point, but if it hangs on it could be decent.
NAM 12z isn't terrible, but the precip shield falls apart completely by hour 50. Kuchera is around 5".
